Since I'm trying to do a couple of I/O processes at the same time, one time
critical and the other not, I need a good time based interrupt to call one
piece of code.  I've been away from pc's too long, but the only timer 
interrupt that I could figure out from the interrupt docs was only every
18.? milliseconds.  I need to call the one process a lot faster than that.

The question:  Can I do this with any method than that which I am currently
considering???  What I think I am going to have to do now is to use an
external clock on the hardware interrupt line on the RS-232 port to call
my subroutine.  There has to be a better way.

Pse e-mail your replies, and thanks very much.
